to wipe out while riding your bike, to have an obscenely bloody accident where one is amazingly able to walk away, to come inches from becoming roadkill, to ride a bike while intoxicated where the likelihood an accident will occur is increased exponentially.

ex 1:
Girl to drunk friend leaving bar on his bicycle: "Dude, be safe and shit - don't toro yourself on the way home!"

Dude friend: "Ah, man - I'm not THAT drunk!"

ex 2:
Girl #1: I'm on lunch, right? and this bike messenger almost gets doored by this fatass getting out of his car. The bike messenger totally swerves but there was this manhole cover there, and you know it had been raining that day, right? dude, he totally toro'ed himself all over the road and was almost run over by this cabbie when he bit it!
